Lead is one of the most environmentally-friendly materials used in the construction industry
Lead sheet is produced from 100% recycled lead also recycled lead has a low carbon footprint and a low energy consuming melting temperature
The initial installation cost of lead is comparable to man-made flashings when the additional expense of adhesives and sealants are taken into account
Lead is quick and easy to install in most weather conditions and requires no adhesive or other fixing materials
Alternatives are very limited in the types of applications that they can be used for, and would not be suitable for more decorative flashings for which lead is renowned
When bossed or dressed correctly lead has few laps or joints resulting in a high degree of weather tightness
Lead lasts up to 100 years and when used for flashings will last three times longer than most man-made products there is little post-installation inspection or maintenance is required
All lead sheet should be coated with patination oil after installation

The Hepworth roll top chimney pot is suitable for domestic fuel fires and appliances. Made from terracotta clay, the high quality natural material adds a traditional character to the building.
Tyvek® Supro is the market-leading breather membrane, helping to protect roofs against wind and water, and also improve energy efficiency. Tyvek® Supro is a durable, water resistant membrane that is reinforced with a laminated polypropylene nonwoven. This airtight, vapour-permeable membrane is extremely water-resistant, and can be used for all supported and unsupported pitched roofs. Tyvek® Supro does not need any soffit, tile or ridge ventilation, which can save time and money in the construction process. In addition to warm, hybrid and cold roofs, applications include Scottish sarking board systems, low-pitched metal roofs, and wall and floor applications. Tyvek® Supro Plus offers the same benefits, plus an integral adhesive lap tape designed for use in the Tyvek® sealed roof system. Sealing all horizontal laps contributes to the system’s thermal efficiency by reducing air infiltration.
Manufactured for us by a world leading gelcoat and flocoat manufacturer. When used with our resins and glass reinforcing achieves FAA fire rating. No extra coverings are required to achieve FAA. Available in mid grey Ral 7046, dark grey RAL 7011 or clear. We can supply in any colour upon request from the BS colour range or the European RAL colour range. Guaranteed for 20 or 25 years depending on resin choice. Available in 20kg, 10kg and 5kg tins.
